a) Three equivalent charges 2.0 micro coulomb each, are held fixed at the three corners of an equilateral triangle of side 5 cm. Determine the Coulomb force experienced at its centre.
b) An electric field of 20N/C exists along the X-axis in space. Measure the potential difference VB-VA where the points A and B are given by (a) A = (0,0) and B = (4,2) metre.
(b) A = (4,2) meter and B=(6,5) metre.
Three charges are arranged on the vertices of an equilateral triangle. Find the dipole moment of the combination ? Take any of two charges and search their dipole moment.(charg
